Abstract Currently, the domestic construction industry is facing issues in a shortage of skilled laborers, an increase in labor costs, a limitation of on-site work hours, and an aging population, which prolongs the construction period and reduces productivity. To resolve these issues, an off-site construction (OSC) method that produces, and transports manufactured components in a factory and assembles them at the site is drawing attention. The precast concrete (PC) method, one of the OSC methods, can handle a larger amount of information at each production stage than the conventional concrete pouring method. For this reason, clear information delivery is greatly needed. However, most PC manufacturing plants and construction sites exchange information by phone, text message, and email; this causes inefficiency and inaccuracy in information exchange. Therefore, it is necessary to develop a new system that enables project managers to transmit relevant information to PC members. In this study, a color visualization method based on the 3D/BIM system was developed for each stage of fabrication, curing, shipment, field and assembly of the PC members. The construction field managers could easily grasp the current state of building elements instantly. In addition, a pop-up function was incorporated in the system to recognize the status of construction in terms of PC member installation. This system was developed to help project managers conduct a simple yet systematic site management. As a result of this study, it is believed that it will improve the difficulty of transmitting information related to PC members, contribute to clearer information exchange, and lower the barriers to the introduction of the OSC method.
